Application filed November I, 1908.

To all whom it may concrn:

Be it known thot I, Rournrr Jnuinxn, 2|, .eitizen of the United States, resident of Cleveland, county of Cuynhogn, end State 5 of. Ohio, have inventor! it new iuul useful Improvement in Distributors, otwhieh the following is a. s eoificntion, the principle of the invention eing herein explained und the. best mode in winch I hove contemploted applying that principle, so usto distinguish it from other inventions.

My invention relates to devices in use in. xcojumetion with internul' combustion, or explosion, motors inwhich an electrical sys tern of i nition. is employed, to tinio the spark w icreby tho charges-in the several cylinders usually composing such engine are. exploded. Such devices hux o been more or less indiilerr-uti} styled circuit controlleis, timers, and distributors.

The object of this infvontion is the. provis n ofa device oi the ubovc L'hnl'udcl' in which eimplicit rof structure hns been coin,-

Diltt'il) upon hose A is mounted u primer on eunlucl-ring .l' (oinpocrd lhroiuglnmt of conl'llu'liln; nultvriul. This ring is connected by moons of u lend u \rilh the ground wire in theroil and for Lin. reason does not require to be insulated from the base of'lhe us distrilniter, such base, along with .-.hnlt. B and the other ports of the nidomobile structure, being all grounded in their, relation in the ignition syoteui'u rircuit. Above prinmr contact. ring A is mounted I0 unothor ring A, n hiyer A of insulntion being interposed between the two rings nud lntcrnlly ineiosing the former, us wullx liiug A", which I shall term the distributor eonhu-r ring, is also counioeod for the nmjor port 0i insulating unite-rial; there nro, how-- ever, eudu-ddrd therein and suitably spaced about its inner circumference an mun) sew nu-niul contact blocks a as there ore cylinderu or spark-plugs to which thr current is so to be SllGCL' SilVBly directed.

The end of distributor shrill 13 is designed to extend within the hollow c lindrirnl spurt iuclosed by the, .suprrimposocl rings A" and A". and upon suchshnltend is :uiustn-bl mounted, by means ol set screws 11, ov u-nd B Iiend B comprise. essentially u sleeve formed on earth sidewith i hurrel b, ouch barrels being disposed pnrnllel with each other and on a. line with primary contact ring. A and distributor contort ring A respectively. They furthernmre open in opposite directions. Within ouch bnrrei is reciprocriblr mounted it brush. or plunger b", the outer end of which is urged Forward intooontzu't with the. odjuoont ring by moons of u s n'iug I)" such brush end being ploned oil or i otten ul so as to narrow its cuntncting four to the width of the oorro-poiuling ring. ilieotrionl connection lHIWttH the, two brushes I)" is insu'redbv joining them through :i iiexiblv coiu'lurtor (1, on shown, Figs. 1 and}. A suitnblo cover, not appearing in [he droningv closes the top of the dislriluuer against the enlrouce. of moisture and dirt.

The operation of the device should be perfectly clear from the foregoin r description of its construction. As the she t B rotates, head B is of course carried with it. During each rotation of the head, brushes b are carried once around their corresponding rings. In the case of ring A, the primary contact ring, this means a continuous electrical connection, whereas in the case of the dislributer ring A, such connection is made only when contact blocks a are encountered The result is an intermittent momentary ilow of current and attendant spark at the eorrespoiuling spark-plug every time the upper brush sweeps across one of the blocks. it is thus seen that I do not depend for the continuity of my current upon the more or less doubtful ability of a four to six volt current, such being the strength ordinarily employed in this connection, to cross the insulating film oi oil that should pro )erly intervene between the shaft Ii and its ea1' ings'. in other words, instead of making the ground connection through such shaft, it is made through a separate conductor a and by terminals, 'i. 0. ring A and lower brush b, that have a continuous metal to metal contact. The disposition of the bruSheSi'urthermore is such as to insure an equal pressure between the members of both sets of'contacting terminals and to equalize the wear on the bearing c by relieving it of all side thrust. The friction between the brushes and the contact rings should be just sullicient to keep the contacting surfaces hright,,and so insure the perfect electrical connection essential to the regular firing of the ascenseharges in the engine cylinders. '1 1e simplieit y before referred to as forming a characteristic of my distributor is evidenced by the fact that by simply removing screws (1 the contact rings may be com )letely disassembled, while a sim ile turn 0 set screws b permits of the brus i-hcad B to be readily adjusted upon, or removed ironnshaftB. This simplicity of construction involves a correspmulillg cconom) in manufacture, and coin bined with the accuracy of operation above pointed out, produces a distribute-rot enhanced value.

Having thus described my invention in dctail, that which I particularly point out and distinctly claim is:

l i In a distributor for an explosion motor, the combination with a support, of axially aliiu-d primary contact and distributor contert rings mounted in said support and insulated from each other, a member rotatably mounted within said rings, and plungers borne by said member and contacting with said rings, respectively.

2. In a distrihuterlor an explosion. motor,

,the combination with a support, oi axially alined primary contact and distributor con tact rings mounted in said support and insulated from each other, a shaft axially mounted with respect'to said rings, a head mounted thereon and oppositely dircrted plunger-s mounted in said head and adapted to contact with said rings respectively. said ]')lllll,0l$ being electrically connected.

3. in a distributer for an explosion motor, the combination with a support, oi axially ulined primary contact and distributer contuct rings mounted in said support and insulated from each other, a shalt mounted in said support so as to extend axially within said rings, a head adjustably mount-ed upon said shalt, said head being, formed with two parallel barrels each on a line with one of said rings, respectively, and opening in opposite directions, to. plunger mounted in each of said barrels, resilient means maintaining said plunger in contact with the corresponding ring, and a flexible conductor electrically connecting said plungcrs.

4. In a distributor for an explosion motor, the combination with a support, of axially alined contact-rings mounted in said 511 port and insulated from each other, one 0 said rings being formed of conducting material throughout and being connected to ground, the other thereof being provided about its inner circumference with spaced contactblocks of conducting material respectively connected with appropriate cylinders of said motor, a shaft mounted in said support so as to extend axially within said rings, a head adjustably mounted upon said shaft, said head being formed with two )arallel barrels each on a line with one of said rings, respectively, and opening in opposite directions, a plunger mounted in each of said barrels, resilient means maintaining said plunger in contact with the corresponding ring, and a flexible conductor electrically connecting said plun- .qers.
